I'll play.
I'm guessing Carl thinks that Hernandez was wrong to call the balk, since Pettitte was throwing to first in order to make a play, which is the allowable exception to the rule prohibiting a throw to an unoccupied base.
I'm not taking a stand on that issue, other than to observe that the customary way for this play to unfold is for F1 to step off before throwing to a base for an appeal.
When Pettitte threw over the second time, the defense had lost their right to appeal the possible base-running error by screwing up the first attempt, and Hernandez made no call. I'm guessing that Carl thinks that this call was correct, or at least correct given the first call.
Carl, you know where to send my prize.
